Pendulum Problem

I got a script to show how the pendulum works,

Code (csharp):

1.  
2.  
3. public enum Path
4.     {
5.         XY, Normal
6.     }
7.  
8.     public Path path;
9.     public float speed;
10.     public float height;
11.     public int freq;
12.  
13. void Start()
14.     {
15.         startPosition = transform.position;
16.     }
17.  
18.     // Update is called once per frame
19.     void Update()
20.     {
21.  
22.         if (transform.position.x < startPosition.x || transform.position.x > startPosition.x + distance)
23.         {
24.             speed *= -1;
25.         }
26.  
27.  
28.         float x = transform.position.x + speed * Time.deltaTime;
29.  
30.         switch ((int)path)
31.         {
32.  
33.             case 0:
34.                 transform.position = new Vector3(x, startPosition.y + SinPathFunc(x - startPosition.x), transform.position.z);
35.                 break;
36.             case 1:
37.                 transform.position = new Vector3(transform.position.x, transform.position.y, transform.position.z );
38.                 break;
39.         }
40.     }
41.  
42.     float SinPathFunc(float x)
43.     {
44.  
45.         float y;
46.         y = height * Mathf.Sin((x * Mathf.PI) / (distance / freq));
47.         return y;
48.  
49.     }
50.  

but i got a problem,
the pendulum is work like this



that a bit not suitable for me
because i wanna make it like this,



so any help?

 

you're only effecting it triginometrically in the y direction, you need to in the x direction as well.

Your x will mostly likely be the Cosine of the angle (this will have a 0 value start you at the top), and your y will be Sine.

You'll have a center point, and you'll add the Cos(x) * radius to the x of the center, and you'll add Sin(y) * radius to the y center.

 

can have the answer more details?
